* X86-64: Add -mskip-rax-setuphjl2014-12-181-0/+13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The Linux kernel never passes floating point arguments around, vararg functions or not. Hence no vector registers are ever used when calling a vararg function. But gcc still dutifully emits an "xor %eax,%eax" before each and every call of a vararg function. Since no callee use that for anything, these instructions are redundant. This patch adds the -mskip-rax-setup option to skip setting up RAX register when SSE is disabled and there are no variable arguments passed in vector registers. Since RAX register is used to avoid unnecessarily saving vector registers on stack when passing variable arguments, the impacts of this option are callees may waste some stack space, misbehave or jump to a random location. GCC 4.4 or newer don't those issues, regardless the RAX register value since they don't check the RAX register value when SSE is disabled. gcc/ * config/i386/i386.c (ix86_expand_call): Skip setting up RAX register for -mskip-rax-setup when there are no parameters passed in vector registers. * config/i386/i386.opt (mskip-rax-setup): New option. * doc/invoke.texi: Document -mskip-rax-setup. gcc/testsuite/ * gcc.target/i386/amd64-abi-7.c: New tests. * gcc.target/i386/amd64-abi-8.c: Likwise. * gcc.target/i386/amd64-abi-9.c: Likwise. git-svn-id: svn+ssh://gcc.gnu.org/svn/gcc/trunk@218870 138bc75d-0d04-0410-961f-82ee72b054a4

Allow pre-increment and pre-decrement on floating point, even if the -mupper-regs-{sf,df} options were used. (rs6000_init_hard_regno_mode_ok): Rework DFmode support if -mupper-regs-df. Add support for -mupper-regs-sf. Rearrange code placement for direct move support. (rs6000_option_override_internal): Add checks for -mupper-regs-df requiring -mvsx, and -mupper-regs-sf requiring -mpower8-vector. If -mupper-regs, set both -mupper-regs-sf and -mupper-regs-df, depending on the underlying cpu. (rs6000_secondary_reload_fail): Add ATTRIBUTE_NORETURN. (rs6000_secondary_reload_toc_costs): Helper function to identify costs of a TOC load for secondary reload support. (rs6000_secondary_reload_memory): Helper function for secondary reload, to determine if a particular memory operation is directly handled by the hardware, or if it needs support from secondary reload to create a valid address. (rs6000_secondary_reload): Rework code, to be clearer. If the appropriate -mupper-regs-{sf,df} is used, use FPR registers to reload scalar values, since the FPR registers have D-form addressing. Move most of the code handling memory to the function rs6000_secondary_reload_memory, and use the reg_addr structure to determine what type of address modes are supported. Print more debug information if -mdebug=addr. (rs6000_secondary_reload_inner): Rework entire function to be more general. Use the reg_addr bits to determine what type of addressing is supported. (rs6000_preferred_reload_class): Rework. Move constant handling into a single place. Prefer using FLOAT_REGS for scalar floating point. (rs6000_secondary_reload_class): Use a FPR register to move a value from an Altivec register to a GPR, and vice versa. Move VSX handling above traditional floating point. * config/rs6000/rs6000.md (mov<mode>_hardfloat, FMOVE32 case): Delete some spaces in the constraints.

Normally constants are put into the pool immediately, but -ffast-math delays putting them into the constant pool for the reciprocal approximation support. (SFmode splitter): Likewise. * config/rs6000/rs6000.opt (-mupper-regs-df): Make option public.

* Preserve original spellings of extended identifiers.jsm282014-11-061-3/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch makes cpplib track the original spellings of extended identifiers, as well as the canonical UTF-8 version, in order to follow standard semantics properly without needing a convoluted and undocumented canonicalization in translation phase 1 (see bug 9449 comments 39-46 regarding such a canonicalization). The spelling is tracked in cpp_identifier and cpp_macro_arg without making cpp_token any larger. The original spelling is used for checks of duplicate macro definitions, stringizing (see the C++ tests added; this case is only an issue for C++ not C because C makes it implementation-defined whether a \ is inserted before the \ of a UCN in a string or character constant when stringizing, while C++ does not), pasting (relevant when the result is then stringized for C++) and when macro definitions are output as text (e.g. for -d options). Once a macro has been defined, only the original spelling of the argument names needs keeping in the argument list. While it is being defined, however, both spellings are needed: the original one for subsequent saving for checks of duplicate macro definitions, and the canonical one which is the node marked specially to generate macro argument tokens rather than normal identifier tokens. The buffer that is used to save the original values of the identifier tokens is changed so that it stores both those original values and a pointer to the canonical hash nodes, so that those canonical nodes can be found when their values need restoring after the macro definition has been parsed. I believe this covers the known standards issues in extended identifiers support (the remaining unimplemented C99 areas in GCC all being floating-point-related), except for C++ translation of extended characters to UCNs in phase 1 (which I have no plans to work on). There are however probably issues left with handling of extended identifiers in other places, as listed in <https://gcc.gnu.org/ml/gcc-patches/2014-11/msg00337.html> (those issues are generally the sort of thing that could be addressed as bugs outside development stage 1). (The bulk of the potential issues Zack was concerned about in 2003-5, that resulted in extended identifiers being disabled in the absence of -fextended-identifiers, were effectively eliminated by the audit and fixes I did in 2009, however; that todo list reflects what was left over after that audit.)

* Enable -fextended-identifiers by default.jsm282014-11-051-5/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | As proposed at <https://gcc.gnu.org/ml/gcc/2014-11/msg00014.html>, this patch enables -fextended-identifiers by default for all standard versions including this feature (all C++ versions, C99 and above for C, but not C90 / C94 / gnu89 / preprocessing assembler). It adds a couple of tests for areas where I previously noted testsuite coverage for extended identifiers was lacking, removes -fextended-identifiers from existing tests, adds -g to various such tests to verify that extended identifiers don't break debug info generation and removes the test that was only there to verify that the feature was off by default. The current state of the feature may not correspond exactly to any particular checklist from 2004/5 (see bug 9449) of what was wanted before enabling the feature by default, but I don't think it's any worse than plenty of other features supported by default before every corner case is fully functional, and think problems can readily be fixed incrementally. The following aspects of extended identifiers could still do with more work (and should be straightforward): * C -aux-info (output should use UCNs). * ObjC -gen-decls (output should use UCNs; associated diagnostics from the ObjC front end should use extended characters or UCNs as appropriate to the locale, via using %qE or identifier_to_locale). * Use DW_AT_use_UTF8 in DWARF-3 debug info for compilation units built with extended identifiers enabled (or unconditionally). * cpplib diagnostics (outputting characters or UCNs as appropriate depending on the locale, as done for identifiers in non-cpplib diagnostics). * C++ test for UCN linking with C and extern "C". * Check GDB support / file issues for support if needed. * Actual UTF-8 in identifiers (?). (Be careful about not affecting performance for the normal fast path of lexing identifiers, if possible.) The following may be trickier: * cpplib spelling preservation (required to diagnose macro redefinition with different spellings of the same identifier in the definition or argument names; different spellings of the name of the macro itself are OK, however; also required for correct handling of multiple stringizing in C++); correct output for -d (UCNs), DWARF debug info for macros (UCNs), PCH and PCH tests. (Spelling preservation is the issue that needs fixing to remove references to corner cases in the documentation of -std=c99 and -std=c11 and in c99status.html.) The idea would be to add a second pointer to cpp_identifier that stores the original spelling (whether for extended identifiers only, or for all identifiers); this does not enlarge cpp_token because the resulting larger cpp_identifier structure is no bigger than cpp_string. * C++ translation of extended characters (including $@` and various control characters) to UCNs in phase 1 (note diagnostics thus needed, but not for C++11, for control characters in strings / character constants as those UCNs invalid); a likely implementation approach is to do translation when identifiers / strings / character constants are lexed, together with errors for stray $@` / control characters in program as not being valid UCNs in identifiers ($ only if not accepted in identifiers); note that this translation should not take place inside raw string literals.

* In cp/error.c, I separate the initialization of the diagnostic contextmanu2014-10-261-5/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | from the initialization of the scratch pretty-printer (cxx_pp). This was suggested by Gabriel in the last review of the patch and now I realize it was a good idea. Now cxx_initialize_diagnostics is the equivalent version of c_initialize_diagnostics. To avoid having to make extern a bunch of functions, I moved it from cp-objcp-common.c to error.c. I moved the setting of diagnostic_format_decoder (global_dc) = c_tree_printer, from c_objc_common_init to c_initialize_diagnostics, and right after c_common_diagnostics_set_defaults. This mimics what is done in cxx_initialize_diagnostics. Moreover, in both c_initialize_diagnostics and cxx_initialize_diagnostics, the FE-specific pretty-printer is initialized first and then other settings are applied. This does not make a difference right now, but if in the future one wishes to touch something in the pretty-printer, it will not get overriden immediately. In fact, the code I removed in c_common_initialize_diagnostics, which sets line_cutoff to 80, is useless because the pretty-printer created here is actually never used, but overriden by the FE-specific pretty-printers. This also means that doc/invoke.texi was wrong. Finally, it is useless to set the maximum line length to 0 in the constructor of cxx_pretty_printer. It is the default anyway. gcc/c/ChangeLog: 2014-10-26 Manuel López-Ibáñez <manu@gcc.gnu.org> PR c++/53061 * c-objc-common.c (c_objc_common_init): Do not do diagnostics initialization here...
